Find the area of the base of a box of height 4cm and lateral surface area 120cm. sq if its length is twice its breadth.

The area of the base of a box is 1800 cm².

Step-by-step explanation:

We have:

H: is the height = 4 cm

: is the lateral surface area = 120 cm

L = 2B                                                                

We can find the breadth of the base by using the lateral surface area and the height:

Now, if the length is twice its breadth we have:

Hence, the area of the base is:

Therefore, the area of the base of a box is 1800 cm².

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
