Question

Find the base of triangle whose area is 42 sq. cm and the corresponding altitude is 12cm​

Answer 1

Answer:

base=7

Step-by-step explanation:

area of triangle=1/2×b×h

42=1/2×b×12

84=12b.

b=7

Answer 2

Given      : 1)Area=42sq cm

                  2)altitude is 12cm​

To Find   :The base

Area of triangle= $\frac{1}{2}\times b\times h$

Therefore,

(1/2)×b×12=42

b×6=42

b=7cm

$\boxed{\textsf Base=7cm}$
