Answer 1

Answer:

Using the formula

A=hbb

2

Solving forhb

hb=2A

b=2·240

48=10m

Answer 2

GIVEN:

● Area of the triangle = 240m²

● Base = 48m

TO FIND:

● Height of a triangle

SOLUTION:

As we know,

$\color{cyan}\boxed{\colorbox{black}{area = 1/2 × b × h}}$

where, b = base of the triangle

h = height of the triangle

ACCORDING TO THE QUESTION:

☆ 1/2 × 48 × h = 240

☆ 48 × h = 240 × 2

☆ 48h = 480

☆ h = 480/48

☆ h = 10

Hence the height of the triangle is 10m.

Hope this helps you...
