Answer 1

Question:

The ratio of base and height of triange is 1:2 and its area is 4989 cm. Find its base and height

Answer:

Given ratio of base and height = 1:2

Let us assume base and height like this

Base = x

Height=2x

Area of triangle= ½ × base × height

According to question,

½ × x ×2x = 49sq.cm

2x² = 49 sq.cm

x = 7 cm

Base = 7 cm

Height = 2 × 7 cm = 14 cm
