The number of units of tiles he will need is 18.96 units
Step-by-step explanation:
The parallelogram ABCD has a right triangle ABD with A as 90°
The length of segment AB is given as 3.16 units and that of the diagonal BD is 7.07 units.
Apply Pythagorean relationship to find length of segment AD=BC
The sum of squares of the sides equals the square of the hypotenuse.
a²+b²=c²
In this case, side a=3.16 units, b=AD and c=hypotenuse=7.07
Applying the formula;
a²+b²=c²
3.16²+b²=7.07²
9.99+b²=49.99
b²=49.99-9.99
b²=40
b=√40=6.3245 =6.32
AD=BC=6.32 units
Find the perimeter of the quadrilateral
=3.16+3.16+6.32+6.32=18.96 units

The cost of 5 bananas and 4 oranges would be $ 27.18
They need to replace 1972 chairs. First you have to multiply 5 x 136. That would equal 680. Then it says a sixth section contains 348. So you would add 680 + 348. That would equal 1028. Then subtract, 3000 - 1028 = 19272.
Hope this helps.
<span>Ishaan is 21, Christopher is 7
No actual question given, but I will assume that the question is "How old are they?". If that's the case, we can create two equations. I'll use I for Ishaan's age and C for Christopher's. I will also assume that there's been some formatting issues here and for some reason, numbers are repeated 3 times without any spaces. So
"Ishaan is 3 times as old as Christopher"
I = 3C
"is also 14 years older than Christopher
I = C + 14
Since both equations are equal to each other, let's set them equal. So
3C = C + 14
2C = 14
C = 7
So Christopher is 7. And we can use the equation I = C + 14 to get Ishaan's age. So
I = C + 14
I = 7 + 14
I = 21</span>
