Pls i need help guys, there is a picture pls as soon as u can

29^2 = 20^2 + AC^2

AC = 21

Area of ABC = (21 * 20 ) / 2 = 210 square centimeters

Volume = (20 * 21 * 300) / 2

Volume = 63,000 cubic centimeters

Step-by-step explanation:

210 cm²

63000 cm³

Step-by-step explanation:

a) A= AB*AC/2

AC= √29²-20²= √441= 21 cm

A= 20*21/2= 210 cm²

b) V=bl

b= 210 cm², l= 3m= 300 cm

V=210*300= 63000 cm³

I think this is what you write:

5g + 4b = $60

3g +  6b = $45

Hope this helps!
