Answer 1

formula of area of triangle=1/2×b×h
1) in first area of triangle is given
540 =1/2 ×40× h
h = 27
2)here height is given
2512=1/2× b×31.4
b= 160
3) here base is given
170.5 =1/2×22×h
h=15.5
4)here base is given
400 = 1/2×20×h
h=40

Answer 2

(1) here base =40 & its area = 500
area of a triangle =1/2×base×height
1/2×40×h=500
h = 500×2/40
h = 25 cm
(2) height = 30 & area = 903.6
1/2×b×30=903.6
b=903.6×2/30
b=6.24 cm
(3) base = 8.4 & area=97.44
1/2×8.4×h=97.44
h=97.44×2/8.4
h=23.5cm
(4) base = 7.8 & area = 3276
1/2×7.8×h=3276
h=3276×2/7.8
h=840 cm
