How many metres of canvas is needed for a rectangular tent of dimension 10x4m x 3m
​

Answer 1

Answer:

Please find the answer below:

Step-by-step explanation:

Given dimensions,

l = 10 m

b = 4 m

h = 3 m

In case of a tent, the base is not considered:

Now,

Area of the tent excluding base =

lateral surface area + top area

2(l+b)h + lb

2(10+4)3 + (10×4)

6(14) + 40

84 + 40

124 m²

Therefore, 124 m² of canvas are required to make the tent.

For this question instead of writing "2(l+b)h + lb"

we can also write it like " 2(lb+bh+hl) - lb ".
