1.	what is the sum of the four exterior angle.The sides of a rectangle are in ratio 4:5.If perimeter of the rectangle is 90cm.Find the sides.
Answer» ratio=4:5 let it be 4x +5x perimeter of RECTANGLE = 2(l+b) perimeter =90cm so,A/Q 90cm = 2(4x+5x) 90cm = 2X9x 90cm =18x X = 90/18cm =5cm first side = 4 X 5cm =20CM second side =5 X 5cm =25 cm Therefore ,the sides of rectangle are: length = 20cm , BREADTH = 25cm

what is the sum of the four exterior angle.The sides of a rectangle are in ratio 4:5.If perimeter of the rectangle is 90cm.Find the sides.

Answer»

ratio=4:5

let it be 4x +5x

perimeter of RECTANGLE = 2(l+b)

perimeter =90cm

so,A/Q

90cm = 2(4x+5x)

90cm = 2X9x

90cm =18x

X = 90/18cm =5cm

first side = 4 X 5cm =20CM

second side =5 X 5cm =25 cm

Therefore ,the sides of rectangle are: length = 20cm , BREADTH = 25cm
