Question

Find the altitude of a triangle if its area is 666 sq. cm and its altitude is 74

Answer 1

Correct Question:

Find the base of the rectangle if its area is 666 cm² and altitude is 74 cm.

Answer:

The base of the triangle is 18 cm.

Step-by-step explanation:

Given :

Area of the triangle = 666 sq.cm

Altitude = 74 cm

To find :

The base

Solution :

Let the base be as y

$\bigstar \: \boxed{\tt{Area = \dfrac{1}{2} \times Base \times Height}}$

$\tt{\implies} \: 666 = \dfrac{1}{2} \times y \times 74 \\ \\ \tt{\implies} \:666 = y \times 37 \\ \\ \tt{\implies} \:666 = 37 y \\ \\ \tt{\implies} \:y = \dfrac{666}{37} \\ \\ \tt{\implies} \:y = 18$

Base = 18 cm

$\therefore$ The base of the triangle is 18 cm.
