Question

7. The height of a parallelogram is one-third of its base. If the area is 108 cm, find the
base and height
8. The area of a rhombus is 119 cmand its perimeter is 56 cm. Find its altitude.
9. One side and corresponding altitude of a parallelogram are 50 cm and 8 cm. If the other
altitude is 4 cm, find the length of other pair of parallel sides.
10. Area of a parallelogram is 625 mFind the length of sides of parallelogram if altitudes
corresponding to sides are 20 m and 25 m.​

Answer 1

Answer:

853

Step-by-step explanation:

108+119=227

227+625=852

Answer 2

Answer:

7 . base = 18 ; height = 6

8. altitude = 8.5

Step-by-step explanation:

7. Area = base x height

108= base x 1/3 base

108 divided by 1/3 = 324

base = root 324 = 18

height = 1/3 x 18 = 6

8. altitude = area divided by  base

base = 56 / 4 = 14

altitude = 119 / 14 = 8.5
