2 ABCDEFGH is a cuboid with a rectangular base in which AB = 12 cm and BC = 5 cm.
The height, AE, of the cuboid is 15 cm.

question:

could we have options?

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

pls mark as brainliest

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
