Question

Find the base of an Isosceles triangle whose area 60 cm Square and length of equal side 13cm

Answer 1

Answer:

9.23 cm

Step-by-step explanation:

Height = 13 cm

Area = 1/2 * b * h

60 = 1/2 * b * 13

60 = 13/2 * b

b = 60*2/13

b = 120/13

Hence base = 9.23 cm

Answer 2

Answer:

Base of an Isosceles triangle=9.23 cm

Step-by-step explanation:

Given:

Height = 13 cm

Using Area formula:

Area = $\frac{1}{2}$×b×h

60 = $\frac{1}{2}$×b×13

60 = $\frac{13}{2}$×b

b = 60×$\frac{2}{13}$

b = $\frac{120}{13}$

Hence base = $9.23 cm$
