Question

I need help to the attachment down below, first answer gets 5 stars and a thanks!

Answer 1

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = $\frac{base*height}{2}$

$52.5 = \frac{base*height}{2}$

$52.5 = \frac{base*7}{2}$

52.5 * 2 = base × 7

105 = base × 7

base = 15

Answer 2

Answer:

15 units

Step-by-step explanation:

From question statement, we observe that

Area of triangle and height of triangle is given.

Area = A = 52.5 square unit    and Height = h = 7 unit.

We have to find the base of triangle.

Base = b =?

The formula to find the Area of triangle is:

Area = 1/2 × base ×height

Hence, base = (2 ×Area ) / height

Putting the given values in above formula, we have

base= (2×52.5) / 7

base = 105 / 7

base = 15 units

15 units is the base of given triangle.
