Answer :

(a) Area of the parallelogram

= base × altitude = 7 cm × 4 cm

= 28 \( cm^2\)

(b) Area of the parallelogram

= base × altitude = 5 cm × 3 cm

= 15\( cm^2\)

(c) Area of the parallelogram

= base × altitude = 2.5 cm × 3.5 cm

= 8.75\( cm^2 \)

(d) Area of the parallelogram

= base × altitude = 5 cm × 4.8 cm

= 24.0 \( cm^2 \)

(e) Area of the parallelogram

= base × altitude = 2 cm × 4.4 cm

= 8.8 \( cm^2\)

- Q.5 PQRS is a parallelogram. QM is the height of Q to SR and QN is the height from Q to PS. If SR = 12 cm and QM = 7.6 cm. Find: (a) the area of the parallelogram PQRS (b) QN, if PS = 8 cm
- Q.6 DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD. If the area of the parallelogram is 1470\( cm^2 \), AB = 35 cm and AD = 49 cm, find the length of BM and DL.
- Q.7 \(\triangle \) ABC is right angled at A. AD is perpendicular to BC. If AB = 5 cm, BC = 13 cm and AC = 12 cm, find the area of\(\triangle \)ABC. Also find the length of AD.
