Answer:
Step-by-step explanation:
The shape can be divided into two parts, let use the division in the question
So we have two rectangles
The area of a rectangle is given by l×b.
Let the big rectangle be 1
And the smaller rectangle be 2
Rectangle 1
Length is 16cm, breadth is 6cm
Area=l ×b
Area=16×6
Area=96cm^2
Rectangle two
The length will be 14-6=8cm
And the breadth will be 16-2=14cm
Then,
Area=l ×b
Area=14×8
Area=112cm^2
Total area is
Area1+Area2
112+96
Total area=208cm^2.
The smallest would be 400,000 and the largest would be the same because 0 can't round up or down

Answer:
Q1. x= 18, y=59
Q2. m∠J= 56°
Step-by-step explanation:
Q1. (3x +5)°= y° (base ∠s of isos. △)
y= 3x +5 -----(1)
(3x +5)° +y° +(4x -10)°= 180° (∠ sum of △)
3x +5 +y +4x -10= 180
7x +y -5= 180
7x +y= 180 +5
7x +y= 185 -----(2)
Substitute (1) into (2):
7x +3x +5= 185
10x= 185 -5
10x= 180
x= 180 ÷10
x= 18
Substitute x= 18 into (1):
y= 3(18) +5
y= 59
Q2. (5x -13)°= (3x +17)° (base ∠s of isos. △)
5x -13= 3x +17
5x -3x= 17 +13
2x= 30
x= 30 ÷2
x= 15
∠LKJ
= 3(15) +17
= 62°
∠KLJ= 62° (base ∠s of isos. △)
m∠J
= 180° -62° -62° (∠ sum of △JKL)
= 56°
