Question

The side of a rectangle find the ratio 4:1
and their perimeter 100m than find the
area of these rectangle​

Answer 1

area is 400m square

side of the rectangle is

2(4x+1x)=100

x= 10

length is 40

breadth is 10

area is 40 multiply by 10

400

Answer 2

Answer:

400m²

Step-by-step explanation:

As sides are in ratio 4:1

Let, l=(4x)m and b=(x)m

Perimeter of rectangle=100m

2(l+b)=100m

2(4x+x)=100

5x=50

So, x=10

l = (4x)m = 40m

b= (x)m = 10m

So, area of rectangle =lb =40×10 m² = 400m²
