Question

find the perimeter area and length of diagonals of a rectangle having length 20 m and breadth 15 m

Answer 1

FIRSTLY AREA OF RECTANGLE =A×B
=15×20=300

SECONDLY DIAGONAL OF RECTANGLE
=(AB ) SQUARE×(BC)SQUARE=(AC)SQUARE
=(15)(15)+(20)(20)=(AC)SQUARE
=225+400=(AC)SQUARE
=625=(AC)SQUARE
=AC=25

Answer 2

perimeter = 2(l+b) = 2X35 = 70n
area l*b = 20 X 15 = 300 meter square
