Question

A rectangular piece of canvas measures
25 cm by 16 cm. A triangular piece,
with base 14 cm and height 10 cm, is
cut off from the canvas. Find the area
of the remaining piece.​

Answer 1

length=25cm and breadth of rectangle =16

area of rectangle =length ✖ breadth

= 25 ✖ 16

= 400cm square

base =14cm and height = 10cm

area of triangle =1/2 ✖ 14 ✖ 10

= 70 CM square

remaining piece = area of rectangle --area of triangle

=400--70 CM square

= 330 cm square

hence, the remaining piece is =330cm square
