Question

i am in class 8 please please please give me the answer so so fast it's very important​

Answer 1

$\bf\fbox\red{ Area of PQRS is 25.5 cm²}$

Step-by-step explanation:

Answer 1

Area ∆PQS = $= \frac{1}{2} \times base \: \times \: height$

Here the base is SQ

Area ∆PQS =

$= \frac{1}{2} \times 7 \times 4 \\ \\ = 7 \times 2 \\ \\ = 14 \: {cm}^{2}$

Similarly Area of ∆ QRS

$= \frac{1}{2} \times base \times height \\ \\ = \frac{1}{2} \times 7 \times 3 \\ \\ = 3.5 \times 3 \\ \\ = 10.5 \: {cm}^{2}$

Area of PQRS = area ∆PQS + Area ∆QRS

$Area of PQRS = area ∆PQS + Area ∆QRS \\ \\ = 14 + 10.5 \\ \\ \bf = 24.5 \: {cm}^{2}$
