Answer:
7x² meters
Step-by-step explanation:
Area = length × width
35x³ = length × 5x
length = 7x²
Look at the picture hopefully it helps at least a little.
Answer:
∠BIJ ≅ ∠CGJ and ∠BJI ≅ ∠CJG
Step-by-step explanation:
We have that the initial triangles are equal. Let us check which components remain within the final triangles as the same. The only such components are the angles B and C. We now know that we have to apply a triangle equality criterion.
The triangles BGH and CIH are equal since the have 2 common sides and the respective interior angles are equal. Then we have that BI=GC and also that the respective angles B and C are equal. THen also HIJ=HGJ since they fill to 180 degrees with angles that are equal.
Hence by angle-side-angle the triangles BJI and CJG are equal.
∠BIJ ≅ ∠CGJ and ∠BJI ≅ ∠CJG
Answer:
95 cm^2
Step-by-step explanation:
perimeter(p)=39cm
L=3x-1
B=2x+3
Now,
p=2(l+b)
39=2(3x-1+2x+3)
39=6x-2+4x+6
39=10x+4
39-4=10x
x=35/10
x=3.5
Putting the value of x
L=3x-1; =3×3.5-1; =10.5-1; =9.5cm
B =2x+3; =2×3.5+3; =7+3; =10cm
Again,
A= L×B
=9.5×10
=95cm^2
