Hope it helps <3
Just basic simplification, make 1 of the variable alone on one side

Answer:
Perimeter = 42 cm.
Step-by-step explanation:
The 2 legs are equal in length as it is an isosceles trapezoid.
Area of trapezoid = (h/2)(a + b) where a and b are the parallel bases.
So
(5/2) (a + b) = 45
a + b = 45 * 2/5 = 18 cm.
We are given that the length of a leg (L) is 2/3 * sum of the bases, so:
L = 2/3(a + b)
= 2/3 * 18
= 12 cm.
The perimeter = a + b + 2L
= 18 * 2*12
= 42 cm.
Answer:
the largest divisor is less than the square root of that number
Step-by-step explanation:
Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61
So divide 937 with all the primes less than 30.61
937/2, 937/3, 937/5,...................937/29
29 would be the largest divisor which is less than the square root of 937 .
29< 30.61
But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.
If any number such 925 is chosen and it gets divided wholly by another prime like 5
925 /5= 185 so it is not a prime number
