a rectangle is 8 ft at the top and on the side its 4.2ft i got 24.4ft for the perimeter and 33.6ft for the area is that corect?

Both of your answers are right! :-)

Find the area of the rectangle 8ft 4.2ft

To confirm if your calculations for the perimeter and area of the rectangle are correct, let's go through the calculations step by step.

The perimeter of a rectangle is calculated by adding up the lengths of all four sides. In your case, you mentioned that the top side is 8 ft, and the side is 4.2 ft. However, it's important to note that the other side opposite the top side should also be 8 ft, and the other side opposite the 4.2 ft side should also be 4.2 ft. So, the perimeter would be:

Perimeter = 8 ft + 4.2 ft + 8 ft + 4.2 ft

Perimeter = 24.4 ft

Therefore, your calculation for the perimeter of the rectangle is correct.

Moving on to the area, the area of a rectangle is calculated by multiplying the length (top side) by the width (side). So, in your case:

Area = 8 ft x 4.2 ft

Area = 33.6 ft²

Hence, your calculation for the area of the rectangle is also correct.

Therefore, both of your calculations for the perimeter and area of the rectangle are indeed correct. Well done!
