Question

A Verandah of area 90 m2 is around a room
of length 15 m and breadth 12 m. The width of
the Verandah is​

Answer 1

Answer:

AREA OF RECTANGLE = L×B×H

L=15 m

B=12m

H=?

90=15×12×h

90=180h

90/180=h

2=h

HOPE THIS IS HELPFUL TO YOU

Answer 2

area of room =2(l+b)

2(15+12)

2*27

54m^2

area of verandah=90m^2

length of verandah=90-54=36

width of the verandah=

2(36+b)=90

36+b=90/2=45

b=45-36=9m
