Answer 1

Answer:

Area of rectangle

Step-by-step explanation:

Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.

Let x = width and x+10 = length

So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.

Thus the area is 5⋅15=75m2
