Question

if two adjacent sides of rectangle are in ratio 4:3 and its area is 192 m square then find its perimeter

Answer 1

Answer:

Step-by-step explanation:

Let the no. be a

4a,3a

Area=l×b

192=4a×3a

192=12a

192/12=a

16=a

Therfore, length=4a(4×16=64)

Breath=3a(3×16=48)

Now, perimeter=2(l+b)

Perimeter=2(64+48)

Perimeter=2(112)

Perimeter=224
