Question

. The base and height of a triangle are in
the ratio 4: 5. If its area is 1000 cm”,
find its base and height.​

Answer 1

Answer:

let the base and height=4x and 5x

area of triangle =1000cmsq

therefore 1/2*4x*5x=1000

2x*5x=1000

10xsq=1000

xsq=100

x=root100

therefore x=10

base of a triangle =4x=4*10=40cm

height of triangle =5x=5*10=50cm

Answer 2

Answer:

baseb=4x

heighth:5x

Area: A = 1/2bh=1000

= 1/2 x 4Xx5x=looo

A =20x2=2000

x2 = 2000/20=100

x =v100 = 10

base4x=4x10=40cm

height=5x=5xlO=50 cm
