2. the Perimeter of a parallelogram is 24 cm . the two adjacent sides are in the ratio 1:2 . the length of the parallelogram is:
3. a square of side 7 cm has a semicircle mounted on the top of 8 the area of the whole figure is
4. if the circumference of a
circle is 44 CM then its area is
5.
the degree of an Arc of a circle is 72 degree if the circumference of the circle is 50 cm then the length of the arc
6. the circumference of a circle with diameter 7 cm is take 5 equal to 22 upon 7
7. ​

Answer 1

Step-by-step explanation:

let the width be x.

then length be x+5

perimeter of parallelogram=sum of all sides

90cm=x+(x+5)

Answer 2

Answer:

x(x+5) = 90

Step-by-step explanation:

x+x=2x

2x+5 = 90

2x=90-5

2x=85

x=85/5

x=17

hence , proved
