Please look over-
1.) Find the area of a rectangle in which the base measures 20 centimeters and the height is half the length of the base.
My Answer= area= 200cm squared
2.) Find the area of a parallelogram in which the height measures 14 inches and the base measures 6 inches more than the height.
My Answer= 68in squared
Thanks. A lot.
Your first answer is correct. 20 * 10 = 200 square centimeters.
The second answer is not correct. The height is 14 inches and the base is 20 inches. The formula is A = b * h
I don't know how I got 68. Would this be correct: a= 280in squared? Or am I still off?
You've got it now. The area of the parallelogram is 280 square inches.
Great! Thank you. Pretty much I really only need help on the circles and that other post below (the one that hasn't been answered) and then I should be done- Finally!=)
I'm going to pass on the post I haven't answered. I'm a little confused about the directions, but perhaps another teacher can help you out.
To find the area of a rectangle, you need to multiply the length (base) by the width (height). Let's go through the process for each question.
1.) Find the area of a rectangle in which the base measures 20 centimeters and the height is half the length of the base.
To find the area of this rectangle, you need to multiply the base by the height. In this case, the base measures 20 centimeters and the height is half the base length.
Step 1: Determine the height
Half the length of the base is equal to 20 cm / 2 = 10 cm. So, the height of the rectangle is 10 cm.
Step 2: Calculate the area
The area of the rectangle = base × height
Substituting the values: area = 20 cm × 10 cm = 200 cm².
Therefore, the correct answer is area = 200 cm².
2.) Find the area of a parallelogram in which the height measures 14 inches and the base measures 6 inches more than the height.
To find the area of a parallelogram, you need to multiply the base by the height. In this case, the base is given in terms of the height.
Step 1: Determine the base
The base measures 6 inches more than the height, so the base = height + 6 inches.
Given height = 14 inches, therefore base = (14 inches) + 6 inches = 20 inches.
Step 2: Calculate the area
The area of the parallelogram = base × height
Substituting the values: area = 20 inches × 14 inches = 280 inches².
Therefore, the correct answer is area = 280 inches².
