Question

PQRS is a parallelogram. QM is the height from Q to SR and QN is the height from Q to PS. If SR = 12cm and QM = 7.6 cm. Find:
( 1 ) the area of the parallelogram PQRS
( 2 ) QN, if PS = 8cm

Answer 1

Answer:

The area of parallelogram is 91.2 square centimeter and length of QN is 11.4 cm

Step-by-step explanation:

Given that PQRS is a parallelogram. QM is the height from Q to SR and QN is the height from Q to PS. If SR = 12 cm and QM = 7.6 cm.

we have to find the area of parallelogram PQRS and QN if PS is 8 cm.

As the area of parallelogram can be calculated by the formula

$Base\times height$

$RS\times QM=12\times 7.6=91.2 cm^2$

Now, we have to find the length of QN

$\text{Area of parallelogram=}PS\times QN$

$91.2=8\times QN$

$QN=11.4 cm$

Hence, the area of parallelogram is 91.2 square centimeter and length of QN is 11.4 cm
