Question

7. If PQ= 4.7cm, RS= 3.2cm then 2PQ - RS is *
O 1.5 cm
O 2.3cm
O 6.2cm​

Answer 1

PQ = 4.7 cm

RS = 3.2 cm

So,

2PQ - RS

= 2×4.7 - 3.2

= 9.4 - 3.2

= 6.2 cm

Answer 2

$\tt \: 7. \: If \: PQ= \orange{4.7cm}, \: RS= \orange{3.2cm} \: then \: \\ \\\tt2PQ - RS \: is \: \underline\red{6.2cm}.$

$\tt▶1.5 cm \\ \\ \tt▶2.3cm \\ \\ ▶\tt6.2cm \: \red{ ✔}$

$\tt \underline{Given}:- \\ \\ \tt \green\bigstar \: PQ = 4.7 \\ \\ \tt\green\bigstar \: RS = 3.2$

$\tt\red{2PQ - RS }\\ \\ \tt \implies 2(4.7) - 3.2 \\ \\\tt\implies9.4 - 3.2 \\ \\ \tt\implies{\underline{\boxed{\bf \orange{6.2 cm}}}}$
