Question

The area of a triangle is 50 m². If the altitude is of 8 cm, what is the length of its base?

Slove this Question please.......plzzzzzzzzzzzz ​

Answer 1

Answer:

we can easily calculate the area of triangle while its length of base and height / altitude is given.

ln this question we we have to find base while altitude and area is given so we can calculate it as:-

As we know that,

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

Where b and h are length of base and height/altitude of triangle respectively.

Here given that,

$area of \triangle =50 {m}^{2} \\ so, \\ \frac{1}{2} \times b \times h = 50 \\ \implies \: b \times h = 100 \\ \implies \: b \times 8 = 100 \\ \implies b = \frac{100}{8} \\ \implies \bold{\blue{\boxed{\boxed{ b = 12.5m}}}}$

Answer 2

Answer:

Area of a triangle ( Right) = 1/2 × altitude × base

50 = 1/2 × 0.08 × base

Base = 100 / 0.08

Base = 1250 cm or 12.5 m
