Question

The length of a rectangular field is 4 times its breadth. Find the area of the field if perimeter is 550 meter

Answer 1

Answer:

12,100m^2

Step-by-step explanation:

Let length be 4x

Let breadth be x

Perimeter =2(l+b)=2(4x+x)

Perimeter =550m

2(5x)=10x=550m

X=55m

Area l×b

l=4x=220

b=x=55

Area =220×55

12100 m^2

Let the breadth if the field be X m.

Therefore the length is 4X m.

Perimeter = 10x = 550m

X = 55m.

L = 220m.

B = 55m.

A = 220 × 55 = 12100 m^2
