Answer:
50ft^2
Step-by-step explanation:
area of triangle ABC=25ft^2
both triangle have equal area and all together it makes a rectangle ABCD so ,
rect. ABCD=25+25=50FT^2
Answer:
x = 4 , y = 1
Step-by-step explanation:
3x + 2y = 14 → (1)
x + y = 5 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 2x - 2y = - 10 → (3)
Add (1) and (3) term by term to eliminate y
x = 4
Substitute x = 4 into (2) and evaluate for y
4 + y = 5 ( subtract 4 from both sides )
y = 1
C
We can see that both triangles occupy exactly half of the rectangle each, so the area of one triangle is half of the area of the rectangle
Answer:
Step-by-step explanation:
3x+4(-0.5x+8)=36
3x-2x+32=36
X=36-32
X=4
