Question

area of a triangle and its hight of base are 1256 square mm and 31'4mmfind the base?​

Answer 1

Answer:

area of triangle = 1/2×base × height

1256 = 1/2 × base× 314

base= 1256 ×2/314

base = 157mm is ur answer.......

hope it is helpful....

Answer 2

$\Huge{\underline{\green{\mathfrak{Ans}}{\mathfrak{wer}}}}$

$\LARGE{\red{\bigstar}} {\underline{\orange{\sf{Given :}}}}$

• Area of triangle is 1256 mm.

• Height of triangle is 31.4 mm.

$\rule{200}{2}$

$\LARGE{\red{\bigstar}} {\underline{\orange{\sf{To \: Find :}}}}$

We have to find the base of the triangle

$\rule{200}{2}$

$\LARGE{\red{\bigstar}} {\underline{\orange{\sf{Solution :}}}}$

We know the formula to find the Area of the triangle.

$\Large{\star{\boxed{\sf{Area = \frac{1}{2} \times Base \times Height}}}}$

_____________[Put Values]

$\sf{→1256 = \frac{1}{2} \times Base \times 31.4} \\ \\ \sf{→1256 \times 2 = Base \times 31.4} \\ \\ \sf{→2512 = Base \times 31.4} \\ \\ \sf{→\frac{\cancel{2512}}{\cancel{3.14}} = Base} \\ \\ \sf{→Base = 80} \\ \\ \implies{\boxed{\sf{Base = 80 \: mm}}}$
