Problem

Find the area of the triangle whose height is 36 cm and the base is \$1/8 th\$ the length of the height.

2

Step

The given height and base is

36 cm & \$1/8\$

3

Step

Now calculate the Base length:

\$(1/8) \times h\$

⇒ \$(36)/8 (cm)\$ = 4.5cm

4

Formula

The formula for the area (A) of a triangle is given by the formula: A = \$(1/2) \times b \times h\$

5

Step

Plug the values into the formula:

A = \$(4.5 \times 36)/2 cm^2\$

A = \$(162)/2 = 81 cm^2\$

6

Solution

Therefore, Area of the triangle is \$81cm^2\$.
