the length of a rectangle is 10 cm longer than the width. what is the area of the rectangle if the width is 15 cm?
A = LW
A = 15(15 + 10)
area=LW=(W+10)W
if W=15cm
area=25*15 cm^2
To find the area of a rectangle, we need to multiply its length by its width. In this case, we are given that the width is 15 cm and the length is 10 cm longer than the width.
Step 1: Let's start by finding the length.
Since the length is 10 cm longer than the width, we can write the length as:
Length = Width + 10 cm
Given that the width is 15 cm, we substitute the value:
Length = 15 cm + 10 cm
Length = 25 cm
Step 2: Now that we have the length and width, we can find the area.
The formula for the area of a rectangle is:
Area = Length × Width
Substituting the values we found:
Area = 25 cm × 15 cm
Area = 375 cm²
Therefore, the area of the rectangle, when the width is 15 cm, is 375 cm².
