Question

the area of triangle is 52.5 cm2 and its height is 7 CM. Find its base. ​

Answer 1

GIVEN:

• Area of triangle = 52.5 cm²
• Height of the triangle = 7 cm

TO FIND:

• What is the base of the triangle ?

SOLUTION:

We have given that, the area of triangle is 52.5 cm2 and its height is 7 cm

We know that the formula for finding the area of triangle is:-

$\large\bf{ Area = \dfrac{1}{2} \times base \times height }$

According to question:-

$\rm{\rightharpoonup 52.5 = \dfrac{1}{2} \times base \times 7 }$

$\rm{\rightharpoonup 52.5 \times 2 = base \times 7 }$

$\rm{\rightharpoonup 105 = base \times 7 }$

$\rm{\rightharpoonup Base = \cancel\dfrac{105}{7} }$

$\large\bf{\rightharpoonup \star \: Base = 15 \: cm\: \star}$

 ❝ Hence, the base of the triangle is 15 cm. ❞

VERIFICATION:

➠ $\bf{ 52.5 = \dfrac{1}{\cancel{2}}\times 15 \times \cancel{7}}$

➠ $\bf{ 52.5 = 15 \times 3.5}$

➠ $\bf{ 52.5 = 52.5 }$
