Question

Area of a triangle is 120 cm². If length of the altitude is 10 cm, then the length of its base
will be
(a) 24 cm
(b) 12 cm
(c) 10 cm
(d) 5 cm​

Answer 1

Answer:

24cm

Step-by-step explanation:

Solution:

Given Data:

The area of triangle is 120cm^2

Length of altitude(height) of triangle is 10cm

b=?

Area of triangle is 1/2*b*h

1/2*b*h = 120

1/2*b*10 = 120

1/2*b = 120/10

1/2*b = 12

b = 12*2

b = 24cm

Answer 2

Answer:

Area = 120cm^2

Altitude = 10 cm

$\frac{1}{2}$ x b x 10 = 120

5b = 120

b = $\frac{120}{5}$

b = 24 cm

Hence the answer is (a) - 24cm
