Question

Find the area of rectangular garden whose perimeter is 200 m and its length is 120 m

Answer 1

perimeter=200m

length=120m

breadth=x

perimeter of rectangular garden =2(l+b)

200m=2(120m+xm)

200/2m=x+120m

100m=x+120m

x=100m-120m

x=-20m

breadth=-20m

area of rectangular garden=(l*b)

area of rectangular garden=(120m*-20m)

area of rectangular garden=-2400m²
