A cause you just gotta think about it and realize you got it
Answer:
a. y + 9 + x + y + x + 4 + x + 5 = 2x + 2y + 18
b. 30.4cm
c. Area of big rectangle = 9y cm², Area of small rectangle = 4x cm²
d. a = 9y + 4x
e. a = 38.8
Step-by-step explanation:
a. Perimeter = y + 9 + x + y + x + 4 + x + 5
= x + x + y + y + 9 + 4 + 5
= 2x + 2y + 18
b. 2x + 2y + 18 = 2(3.4) + 2(2.8) + 18
= 6.8 + 5.6 + 18
= 30.4cm
c. Formula for area of rectangle: length × breadth
Area of big rectangle = 9 × y
= 9y cm²
Area of small rectangle = 4 × x
= 4x cm²
d. a cm² = (9y + 4x)cm²
e. a = 9y + 4x
= 9(2.8) + 4(3.4)
= 25.2 + 13.6
= 38.8
To answer this question you would need to use PEMDAS. Since you don't have any parentheses or exponents, you would start by doing all division from left to right. After that you would do the subtraction from left to right. Your final answer should be -13.5
