Question

The area of a triangle is 90 cm^2. If its base is 15 cm, find its altitude.​

Answer 1

Answer:

Area = 1/2 × base × height

90cm^2=1/2 × 15 ×height

Height=90 × 2 / 15

Height = 6× 2= 12 cm

Step-by-step explanation:

This is the answer

Answer 2

Answer:

1080 cm

Step-by-step explanation:

Area of triangle = 1/2 *b*h =90^2=8100

$\frac{1}{2?} \times b \times h \: = 8100 \\ \\ \frac{h}{2?} \times 15 = 8100 \\ h \: \frac {8100}{?15} \times 2 \\ h = 1080$
