Question

The base of the parallelogram is thrice its height,if the area is 192 cm2 . find its base and height

Answer 1

let base be 3x and height be x
Area of llgm=b×h
192cm²=3x×x
192=3x²
x²=192/3
x²=64
x=√64
x=8
base=3x=3×8=24cm
height=x=8cm

Answer 2

let the height be x . Then base= 3x
Area =base *height
Therefore,
3x *x= 192
3x2=192
= 192/3
x2=64
x=√64
x=8

therefore, height=8cm and, base =24cm
