Question

if area of a triangle is 56 m square and height is given 7 cm then find its base​

Answer 1

Answer:

A = 1/2 B x H

56 = 1/2 B x 7

56 = 7/2 B. Multiple both sides by 2/7

B = 56 x 2/7

B = 8 x 2 = 16

Answer: 16m

Check: 56 = 1/2 (16) x 7 = 8 x 7 = 56. Yes

Answer 2

Answer:

Base of a triangle is $16$ m.      

Step-by-step explanation:

Given : Area of a triangle = $56$ $m^{2}$  

          Height = $7$ m

To find : The base of a triangle.

Solution :

• It is given that the area of a triangle = $56$ $m^{2}$    

          Height = $7$ m

• We have to find the base of a triangle.
• For a triangle, we know the formula for area of a triangle and is given by,

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

                           $56=\frac{1}{2} *b*7$

                        ∴ $56 = \frac{7}{2} *b$

                     ∴ Base $= 56*\frac{2}{7}$

                     ∴ Base $= 16$ m

• ∴ Base of a triangle is $16$ m.
