Answer 2

Answer:

(i) 3 cm

(ii) 68 cm^2

Step-by-step explanation:

(i) Explanation:

• The lower side = 11 cm
• The upper side = 8 cm

Therefore, 11 = 8 + x   is the equation formed.

Hence, x = 3 cm.

(ii) Explanation:

Area of a rectangle = length x breadth

∴ Area of rectangle A = 8 cm x 7 cm

                                    = 56 cm^2

∴ Area of rectangle B = 4cm x 3 cm     [got from eq. (i)]

                                    = 12 cm^2

∴The area of the total shape = Area of A + Area of B

                                                = 56 cm^2 + 12 cm^2

                                                = 68cm^2

I hope you got your answer. Thank You!
