Question

find the base of a triangle whose height is 20cm and area is 150cm²​

Answer 1

Answer:

given the altitude of the triangle = 20cm and area of the traingle is = 150cm²

we know the formula for solving for the area of a triangle, that is 1/2 × b × h where b is the base of the triangle and h us the altitude of the triangle.

therefore 1/2 × b × h = 150cm²

==> 1/2 × b × 20 = 150cm²

==> 20b = 150 × 2

==> 20b = 300

==> b = 300/20

==> b = 15

hence, the base of the triangle is 15cm.

Hope it helps uhh

Answer 2

ANSWER:

EXPLANATION:

area = 150 sq. cm

height = 20cm

are of triangle = 1 × base × height

2

150 = 1 × base × 20

2

150 × 2 = base

20

15 = base

base = 15 cm
