Question

area and perimeter is 270 metre square and 96 meter. if one side of a parallelogram is 18 metre .find the length of other side and also find the altitude.
above is the parallelogram drawing
​

Answer 1

Given,

Perimeter of parallelogram =96m

Area of parallelogram =270sq.m

In parallelogram ABCD

AB=CD=18m and AD=BC

As we know perimeter one parallelogram ABCD=AB+BC+CD+AD

⇒96=18+AD+18+AD

⇒96=36+2AD

⇒AD=BC=

2

60

=30m

Now, area of parallelogram ABCD,

⇒270=AB×DE

⇒DE=

18

270

⇒DE=15m

∴m=15 m

Also, area of parallelogram ABCD,

⇒270=30×l

⇒l=

30

270

⇒l=9m

Answer 2

Step-by-step explanation:

Area = 270 m²

Perimeter = 96 m

Finding the other sides

96 = 2×18 + 2x

96 = 36 + 2x

96-36 = 2x

60 = 2x

30 =x

Hoping that 30m is for the base

Finding the altitude(H),

H = 270÷30

= 9m
