using a formula estimate the body surface area of a person whose height is 5 feet and who weighs 120 pounds.
a.
1.52 m2
b.
0.32 m2
c.
1.13 m2
d.
55.9 m2

(A)  1.52 m²

Step-by-step explanation:

As per the given data of the question,

Height of a person = 5 feet

As we know that 1 feet = 30.48 cm

∴ Height = 152.4 cm

Weight of a person = 120 pounds

And we know that 1 pound = 0.453592 kg

∴ Weight = 54.4311 kg

The Mosteller formula to calculate body surface area (BSA):

Therefore,

Hence, the body surface area of a person =  1.52 m²

Therefore, option (A) is the correct option.

step-by-step explanation:

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.
