Question

a rectangular box has height h cm its length is 3 times the height and breadth is 8 cm less than the length express the length and the breadth of the box in terms of the height ​

Answer 1

(a)

(i) y+5

(ii) y–3

(iii) 6y

(iv) 6y–2

(v) 3y+5

(b) Length = 3b and Breadth = (3b–4) meters

(c) Height of the box = h cm

Length of the box = 5 times the height = 5h cm

Breadth of the box = 10 cm less than length = (5h–10) cm

(d) Meena’s position = s

Beena’s position = 8 steps ahead = s+8

Leena’s position = 7 steps behind = s–7

Total number of steps = 4s–10

(e) Speed of the bus = v km/h

Distance travelled in 5 hours = 5v km

Remaining distance = 20 km

Therefore, total distance = (5v+20) km
