Question

Find the area of a rectangle if the perimeter is 36m, the length=(x+5)m and the breath=(x+3)m​

Answer 1

Answer:

80m^2

Step-by-step explanation:

perimeter=2(X+5+X+3)

36=2(2x+8)

18=2x+8

X=5

length=10m

breadth=8m

area =10×8= 80m^2

Answer 2

Answer:

80m^2

Step-by-step explanation:

Perimeter = 2( (x+5)+(x+3))

36= 2(2x+8)

18=2x+8

10=2x

X=5

So length=10

Breadth=8

And area = length* breadth

=10*8 = 80
