Answer 1

Given :-

• Area of the triangle = 126 cm²
• Base of the triangle = 56 m

To Find :-

• Height of the triangle.

Solution :-

Area of the triangle :-

$\green{:\implies\:\:\:}\sf{Area = \dfrac{1}{2} \times base \times height }$

$\green{:\implies\:\:\:}\sf{126 = \dfrac{1}{2} \times 56 \times h }$

$\green{:\implies\:\:\:}\sf{126 = 28 \times h }$

$\green{:\implies\:\:\:}\sf{h= \dfrac{126}{28} }$

$\green{:\implies \:\:\:}\underline{\boxed{\pink{\mathfrak{h = 4.5\:m}}}}$

∴ Height of the triangle = 4.5 m

To check ↓

Area of the triangle :-

$\blue{:\implies\:\:\:}\sf{Area = \dfrac{1}{2} \times b \times h }$

$\blue{:\implies\:\:\:}\sf{Area = \dfrac{1}{2} \times 56 \times 4.5 }$

$\blue{:\implies\:\:\:}\sf{Area = 28 \times 4.5 }$

$\blue{:\implies\:\:\: }\underline{\boxed{\purple{\mathfrak{Area = 126 \:cm^2}}}}$

Hence Verified! :D

Answer 2

${\large{\underbrace{\underline{\bf{Question:-}}}}}$

If the area of the triangle is 126 m² and base is 56m, find its height.

${\large{\underbrace{\underline{\bf{Answer:-}}}}}$

Given:-

• Area of triangle = 126 m²
• Base of triangle = 56 m

To find:-

• Height of the triangle

We know that,

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

126 = $\frac{1}{2}$ × 56 × h

126 × 2 = 56 × h

252 = 56 × h

h = $\frac{252}{56}$

∴ h = 4.5 m

Hope this helps! ♡
