Question

please solve my question in simplest way ​

Answer 1

Answer:

6cm.

Step-by-step explanation:

Given:

Area of triangle PQR = 20sqcm.

Area of triangle PQS = 44sqcm.

QR = 5cm

Area of tringle PQR = 1 x b x h

2

= 1 x 5 x h = 20

2

= 5h = 20 x 2

= h = 40 = 8cm.

5

Simlarly,

Area of triangle PQS=

= 1 x b x h

2

= 1 x b x 8 = 44

2

= 8b = 88

= b = 88 = 11cm

QS = 11cm.

Thus,

RS= QS - QR

RS = 11 - 5

RS = 6cm.
