Ipatiy [6.2K]

Answer:

2.38 miles

Step-by-step explanation:

From Given diagram:

In ΔABC,

AC=2.5 miles

BC= 3.7 miles

∠BCA= 39.4°

Now as we have two sides and an angle, using law of cosines to find the third side:

c= √(a^2+b^2-2abcosα

AB=√(AC)^2 + (BC)^2 - 2(AC)(BC)cosα

=√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)cos(39.4°)

=√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)(0.77)

=√(5.695)

= 2.38 !

Answer:

522 m^2

Step-by-step explanation:

I've circles the numbers that you actually need to solve this problem.

First, find the area of the bigger rectangle by multiplying the length and width.

24*21=504

Then find the area of the smaller rectangle the same way

3*6=18

then add them to get the total area

504+18=522

522 m^2
