Question

the area of a triangle is 90 cm square if its base is 15 cm find its altitude​

Answer 1

Step-by-step explanation:

Area of triangle=90 cm.

Base=15cm.

Height=?

The area of triange= 1/2×base×height

90cm=1/2×15cm×x

90cm×2=15cm×x

180cm=15cm×x

X=180/15

X=12

Answer 2

area = 90cm sq

base = 15cm

altitude = h

Area of triangle = 1/2 x b x h

=

90 = 1/2 x 15 x h

90 x 2 = 15 x h

180 = 15h

h = 180/15

h = 12cm

Altitude = 12cm
