Question

Ouadrilaterals
1. The sides of a rectangle are in the ratio 5 : 4 and its perimeter is 90 cm. Find its
length and breadth.
2. The angles of a quadrilateral are in the ratio 1:2:3:4.Find the each angle.
​

Answer 1

a )let the sides be 5x,4x,5x and 4x

given that 5x+4x+5x+4x=90

=> 18x=90

=>x=90/18

=>x=5

therefore the sides are 25 cm,20 cm,25 cm,20 cm

b) let the angles be x,2x,3x and 4x

as we know that angles of a quadrilateral is equal to 360 degree

so

=>x+2x+3x+4x=360

=>10x=360

=>x=36

therefore, the angels are 36 ,72, 108 , 146
