Question

A rectangle and a parallelogram are drawn between the same parallel lines on a common
base of 10 cm. If the perimeter of the rectangle is 36 cm. Find the area of the parallelogram.
2 om and 20 cm and non-​

Answer 1

Step-by-step explanation:

If the perimeter of the rectangle os 36cm find the area of the area of ... rectangles base will also be 10 cm(because same base) so ... So area of rectangle=8 x 10= 80cm^2.

Answer 2

Answer:

80 cm^2

Step-by-step explanation:

perimeter of rectangle=36 CM

=> 2(l+b) = 36 CM

=>2(l+10) =36

=>l+10=18

=> l=18-10

=I l= 8 cm

Now, since rectangle and parallelogram are on the same base and same parallel so their area will also equal.

Area of parallelogram =Area of rectangle

Area of parallelogram =l×b

Area of parallelogram = (8×10 ) cm^2

Area of parallelogram =80 cm^2
