Class- 8th
Topic- Mensuration

Answer 1

Answer:

121 cm^2

Step-by-step explanation:

Let us first find the area of the rectangle: 18 x 4

                                                             = 72                                                            

The area of the two triangles : 2 x 4 x 1 x 1/2

                                            = 4

Area of Triangle STR = 5 x 18 x 1/2

                                  = 45

Total Area = 45 + 4 + 72

                = 121 cm square

Answer 2

ar(TSR) = 1/2 ×18 × 5

=> ar(TSR) = 45 CM²

ar(rectangle) = 18 × 4 = 72 cm²

ar of both side triangle = 2× 1/2 ×2× 4

= 8cm²

Total area = 45+72+8 = 125cm²
