Question

find the base of the triangle whose area and height at
(a) Area = 1275 m² height =17 m
area and height are given below.
(b) Area 3420 cm², height 57 cm​

Answer 1

Answer:

in 1st question

area of triangle=1/2*base *height

1275=1/2*base*17

1275*2/17=base

150m = base

(b) similar

area of triangle=1/2*base*height

3420*2/57= base

120cm=base

Answer 2

${ \mathbb{WE \: \: KNOW,}}$

Area of triangle = $\bf{ \frac{1}{2} \times (base) \times (height)}$

$\\ \bf 1.Base = \frac{2 \times Area}{Height} \\ \\ \bf = > \frac{2 \times 1275}{17} = 2 \times 75 \\ \\ \bf= > 150 \: m$

$\\ \bf 2.Base = \frac{2 \times Area}{Height} \\ \\ \bf = > \frac{2 \times 3420}{57} = 2 \times 60 \\ \\ \bf= > 120 \: m$
