I don’t know ans of 17 number say me answer

Area of the bigger rectangle =(18×8)cm

2

=144cm

2

Area of the smaller rectangle =((30−18)×(8−6))=(12×6)cm

2

=72cm

2

∴ Total area = area of smaller rectangle + area of bigger rectangle =(72+144)cm

2

=216cm

Step-by-step explanation:

the area of bigger rectangle is given by L*W

it simply means that length of larger rectangle multiplied by width of larger rectangle

=20*16

=320m2

hence the path between the lager and smaller rectangle is given by

the path is twice

hence it will be 2*2

=4m

smaller length is

20-4

=16m

smaller width is

16-4

=12

hence area of smaller rectangle

l*w

=16*12

=192m2

hence area of shaded path is given by

=320-192

=128m2

taking larger area of rectangle -the smaller area of rectangle

the answer is d. 75%

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
