(b) Area = 395 cm, height = 12.5 cm base =?
(c) Area = 351 m. base = 156 m. height=?
(d) Area = 4440 cm, height = 74 cm, base =?
7.2 cm
the following parallelograms.
a Find the missing elements of the following parallelograms based on the​

Answer 1

Step-by-step explanation:

A = ½ × b×h, b and h indicate base and height respectively.

(a) 121.5 = ½ × 16.2 × h

=> h = 121.5×2/16.2 = 15m

(b) 395 = ½ × b × 12.5

=> b = 395×2/12.5 = 63.2 cm

(c) 351 = ½ × 156 × h

=> h = 351 x 2 / 156 = 4.5m

(d) 4440 = ½ × b × 74

=> b = 4440 × 2/74 = 120cm
