Question

pls answer fast 16,17,18,20,22

Answer 1

16)length=3x
breadth=x
perimeter of rectangle=2 (l+b)=2 (3x+x)=2 (4x)=8x
8x=162
x=192÷8
x=24

then length=3x
=3 (24)=72
breadth =24




18)1st angle =44degrees
2nd angle=?

supplementary angles =180degrees

2nd angle =1st angle-180=180-44=136degrees


20)denominator=3x
numerator=x

and after adding the given values to numerator and denominator then,

denominator=5x+3x=8x^2

numerator=2x^2

then,2x^2÷8x^2

x^2=1÷4 is the fraction after bringing that square to this side then the answer will be 1÷2

x=^2 1/4
then x=1/2,.

I hope it will help for u ☺.
