Question

perimeter of rectangle is 151m.if breadth is 32.find lenth​

Answer 1

Given

Perimeter of Rectangle is 151m

Breadth of Rectangle is 32m

To Find

Length of Rectangle

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Perimeter of Rectangle =2(length +breadth)

=>Perimeter of Rectangle =2(l +32)

=>151=2(l+32)

=>151/2=l+32

=>151/2-32=l

=>151-64/2=l

=>87/2=l

=>43.5=l

∴Length of Rectangle is 43.5m

Check

Perimeter of Rectangle=>2(43.5+32)

Perimeter is the total distance occupy by a solid 2D figure around its edge.

Answer 2

Given:-

Perimeter of Rectangle is 151m

Breadth of Rectangle is 32m

To find:-

Length of Rectangle

SOLUTION :-

__________

Perimeter of Rectangle =2(length+breadth)

=>Perimeter of Rectangle =2(l +32)

=>151=2(l+32)

=>151/2=l+32

=>151/2-32=l

=>151-64/2=l

=>87/2=l

=>43.5=l

∴Length of Rectangle is 43.5m

Perimeter of Rectangle=>2(43.5+32) =151m

Extra information=>
