Question

Find the area of a rectangle whose perimeter and length are 200 m and 30 m respectively

Answer 1

Answer:

area=2100 m²

Step-by-step explanation:

Given, L= 30 m, perimeter =200 m

We know, perimeter of rectangle = 2×(L+B)

Therefore,

2×(L+B)=200

2×30+2B=200

2B=200-60

B=140/2

B=70

Area=L×B=30×70=2100 m²
