Question

the base and height of a triangle are in the ratio of 4: 7. If the area of the triangle is 171.5 cm. find
its base and height​

Answer 1

Answer:

let the base and the height of the triangle be 4x and 7x we know that area of triangle is half into b into h

therefore 171.5=1÷2× 7x × 4x

171.5÷14=x2

12.5=x2

root of 12.5=x

therefore X is equals to 3.5

hence base is 4 into 3.5 that is 14 centimetre and height is 7 into 3.5 that is 24.5 centimetre

Answer 2

Answer:

1/2*b*h

Step-by-step explanation:

B=4 x, h=7x

Area of traingle =1/2*4x*7x

171.5=14x^2

12.25=x^2

X=3.5

bx=3.5*4=17ans

hx=3.5*7=24.5 ans
