​

Answer 1

Answer:

85metre answer correct

Answer 2

Answer:

₹1200

Step-by-step explanation:

length of room = 8m

width of room = 5m

area of room = 40m²

both the length of varandah = 8m,8m

both the width of varandah = 2( 5-3 ) = 2m,2m

(it is because , the length part of the varandah has width which will already be taken during finding the area of the length side of the varandah , so we don't need to take the width of the varandah as the length of the width side of the varandah .)

area of the length part of the varandah

= 2(8×1.5)m²

= 2×12m²=24m²

area of the width part of the varandah

= 2(2×1.5)m²

= 6m²

total area = 30m²

therefore, cost to flore 1m² = ₹40

cost to flore 30m² =₹ 40×30

= ₹1200

hope it helped
