Question

rectangle and a square have equal perimetera . if the breadth of the rectangle is 10 cm and the side of the square is 15 cm, then find the difference between their areas. find the height of the cuboid whose volume is 275 cube cm and base area is 25 sq cm

Answer 1

4×15=2×10+2×l
then length =20
difference =25

Answer 2

1 ANSWER
PERIMETER OF SQUARE = PERIMETER OF RECTANGLE
4×15=2(10+LENGTH)
2×15=10+LENGTH
LENGTH=20C.M

AREA 1 - AREA2=225-200
=25C.M^2

2 ANSWER
VOLUME=BASE AREA ×HEIGHT
275 =25×HEIGHT
HEIGHT=275/25
=11C.M
